The Problem with Factory Farms
By Claire Suddath, courtesy of TIME
If you eat meat, the odds are high that you’ve enjoyed a meal made from an animal raised on a factory farm (also known as a CAFO). According to the USDA, 2% of U.S. livestock facilities raise an estimated 40% of all farm animals. This means that pigs, chickens and cows are concentrated in a small number of very large farms. But even if you’re a vegetarian, the health and environmental repercussions of these facilities may affect you.

What exactly is a factory farm?
The industrial model for animal food production first started with the poultry industry. In the 1930s and ’40s, large companies got into the farming business. The companies hire farmers to grow the animals for them. The farmers typically don’t own the animals — the companies do. It’s almost like a sharecropping system. The company tells them exactly how to build the farm, what to grow and what to feed. They manage everything right down to what temperature the barn should be and what day the animals are going to be picked up for slaughter. The farmer can’t even eat his or her own animals. People who grow chickens for Perdue in Maryland have to go down to the market and buy Perdue at the store.
We collectively refer to these facilities as factory farms, but that’s not an official name. The government designation is CAFO, which stands for Concentrated Animal Feeding Operation. Basically, it’s any farm that has 1,000 animal units or more. A beef cow is an animal unit. These animals are kept in pens their entire lives. They’re never outside. They never breathe fresh air. They never see the sun.

EPA Study: Autism Boom Began in 1988, Environmental Factors Are Assumed

EPA Study: Autism Boom Began in 1988, Environmental Factors Are Assumed

If it seems like most of the people you know with autism are 22 or younger, that’s because most people diagnosed with autism were born after 1987. A recent US EPA study has found a distinct "changepoint" year – or spike – in autism in California and elsewhere and concludes that it would be "prudent to assume that at least some portion of this increase is real and results from environmental factors."
"In the Danish, California, and worldwide data sets, we found that an increase in autism disorder cumulative incidence began about (the birth cohort years) 1988-1989," wrote the authors Michael E. Mc Donald and John F. Paul, of the EPA’s National Health and Environmental Effects Research Laboratory.
"Although the debate about the nature of increasing autism continues," they added, "the potential for this increase to be real and involve exogenous (external) environmental stressors exists."
But it was the distinct timing in the increase of autism – the birth of an epidemic, as many believe – that was most notable, and which "may help in screening for potential candidate environmental stressors."
"The calculated year was determined to be significant," the EPA scientists said. The rate of increase before 1988 "was significantly different" than the rate after that year (the "postchangepoint," in epidemiology parlance). In California, the rate spiked from 5.7-per-10,000 before the changepoint, to 20.8-per 10,000 in its wake, and the worldwide dataset showed a similar jump (from 6.0 to 24.2). In Denmark, the rise was even more dramatic, though total incidence was only a fraction of that in the US: from 0.6 to 6.6.
(A study in Japan from 1988-1996 showed continuously increasing autism rates, but no calculable changepoint year – please see the full report for a discussion on study limitations).
So why would rates more than triple in California kids born before and after 1988? Is…
